1. IMPORTANT REMARK

We thank you for trusting on us and choosing our COMPACT 5 mixer. In order to get

the most in operation and efficiency from your mixing unit, it is VERY IMPORTANT for you -

before you plug anything - to read this manual very carefully and take seriously into account all

considerations specified within it.

In order to guarantee the optimum operation of this unit, we strongly recommend that

its maintenance be carried out by our Authorised Technical Services.

1.1. Safety Precautions

This apparatus must be earthed through its mains cable.

Do not expose the unit to rain or water splashes, and do not place liquid containers or

incandescent objects like candles on top of the unit. Do not obstruct the ventilation

shafts with any kind of material.

Any change in the configuration of the unit must be carried out by a qualified technician.

Should any connection / disconnection task be done, always disconnect the unit from the

mains supply.

There are no user serviceable parts inside the unit.

2. INTRODUCTION

The Compact 5 merges flexibility, simplicity and ECLERs renowned quality into an

universal mixer which has been specially designed for non-technical users: The COMPACT 5.

This simple and intuitive mixer is suited for a broad variety of installations, ranging from

conference rooms or church sound systems to outdoor P.A., children entertainment,

presentations or fashion shows to name a few.

Its reduced size and the specially designed chassis make it ideal both for rack

mounting or as a table-top unit. Last but not least, the technological concept and the carefully

selected electronic components make this mixer a 100% professional unit.

The COMPACT 5 incorporates 5 mixable channel, each with different input capabilities:

Channel 1 LINE A and LINE B LINE B switchable to PHONO from rear panel

Channel 2 LINE A and LINE B LINE B switchable to PHONO from rear panel

Channel 3 LINE / MICRO / AUXILIARY AUXILIARY on front panel

Channel 4 LINE / MICRO

Channel 5 LINE / MICRO Additional MICRO input on front panel

All channels feature a lever switch input selector, independent gain control and 3

band tone controls.

All inputs are PFL capable in order to visually (through the VU meters) and

acoustically (through headphones) monitor any signal connected to the inputs of the unit.

3. INSTALLATION

3.1. Placement and mounting

The first thing to take into account when looking for the placement of the

COMPACT 5 is your comfort and an easy access to all the connections.

The COMPACT 5 has 19" (482.6 mm), 3U (132.5 mm) rack mounting ears that allow

you to place it in a standard rack.

Because of the high gain of the PHONO and MIC inputs, the mixer must be placed as

far as possible from noise sources (dimmers, engines, etc.) as well as from any mains cable.

You should never, under any circumstance, remove the metallic cover of the mixer.

The COMPACT 5, being a low consumption unit, does not need any cooling; you

should anyway avoid exposure to extreme temperatures and the operating environment must

be as dry and dust free as possible.

The COMPACT 5 operates under voltages between 90 and 264 V at 47 to 63 Hz.

This device features an over dimensioned power supply that adapts to the mains voltage in any

country of the world with no need to make any adjustments.

In order to protect the mixer from eventual mains overloads, it has a time-lag 0,5 A

(26) mains protection fuse. Should this fuse ever blow off, disconnect the mixer from mains

and replace it with an identical one. NEVER REPLACE THE FUSE WITH ANOTHER ONE WITH A

HIGHER VALUE.

ATTENTION: Changing the fuse must be performed by qualified technical personnel.

3.2. Connectable Signal Sources

- Turntables / Phono: They must be fitted with a magnetic cartridge with nominal

output level between -60dBV and -20dBV (1 to 100 mV). The PHONO (36) inputs of the

COMPACT 5 have a high headroom (margin before saturation) and it can handle higher output

cartridges than what is usual. These inputs are supplied with a nominal input sensitivity of

-40dBV (10mV).

- Microphones: The MIC inputs (20-33) are ready for a nominal input level of -50dBV

(3.16 mV) and are equipped with COMBO connectors. The COMBO connector provides both a

XLR plug and a ¼’’ Jack in the same receptacle. The connection of balanced signals is as

follows:

XLR-3 ¼‘’ Jack

Hot or direct signal > Pin 2 Tip

Cold or inverted signal > Pin 3 Ring

Ground > Pin 1 Sleeve

Low impedance (200 to 600) monophonic microphones must be used. In case of

working with an unbalanced connection, the ground pin and Pin 3 (or the ring) must be short-

circuited.

The COMPACT 5 features a Phantom power supply for the connection of condenser

microphones. A switch for general activation of the phantom power can be found on the front

panel of the unit (14) and can be activated using a sharp-pointed object.

6

-LINE Inputs. The sensibility of the line inputs (18-34-36-37) is rated at 0dBV (1V).

CD, DAT, MP3, DVD Audio Players, Tape recorders, cassettes, tuners or videos should be

connected to LINE inputs.

Additional line level sources may be connected to the “AUX IN 3” input, which is

located on the front panel and is electrically linked to channel 3.

- Headphones: In order to achieve the best performance, they should be high

impedance type (200-600). They must be connected to the headphones out (17) connector, a

standard ¼" stereo jack. Connect ground to sleeve, ring to right and tip to left.

- Power amplifiers: See paragraph 4.6.

4. OPERATION AND USAGE

4.1. Start up

Power up the mixer by pushing the POWER (11) switch. The green pilot-light,

integrated into the switch itself, will immediately light up. Although the noise generated by

powering up the COMPACT 5 is reduced to a bare minimum and is nearly null with the

OUTPUT (12 and 15) controls down, it is always advisable not to forget about this power-up

sequence: sound sources, mixer, equalizers, active filters and power amplifiers. Power down

the equipment by following the inverse sequence. This way the peaks or transients produced

by powering up / down a device do not affect the following one in the audio chain and, as a

result, they do not reach the loudspeakers, which are the most vulnerable audio elements in

this case.

4.2. Monitoring

The COMPACT 5 is equipped with an acoustical and visual monitoring system,

through headphones and VU METER. When switching ON any of the PFL buttons (23), signal(s)

present at the input(s) will be heard through the headphones and seen on the VU METER. If no

switch is at the ON position, the signal present at the main mix bus is monitored (open faders).

4.3. Channel gain and equalization

These controls allow individual input sensitivity and tone adjustments for each

channel.

Thanks to the GAIN (2) control, you can precisely adjust the signal level of an

incoming musical signal to match the level of the music that is playing on air through another

channel. This operation may be performed visually (through the left VU-meter) and acoustically

(through the headphones), successively comparing both signals with the PFL buttons. The Gain

knobs offer an adjustment range of ±20dB.

The three band tone controls (1-3-25) affect bass, mid and treble frequencies and

offer a ±15dB variation range. Please be careful when using the tone controls in order not to

overload the loudspeakers.

4.4. Channel indicators

Each of the five input channels features two indicators. The green signal LED (4)

shows the presence of signal on the currently selected input. The indicator lights up at a

threshold of –40 dBV. The red peak LED (6) warns about the risk of saturation, that is

exceeding the recommended signal input level limit. This LED may sporadically flash without

risk of damaging the unit, but it should never stay lit continuously. This indicator lights up at a

threshold of 10dBV

4.5. Talkover

This device automatically reduces the signal level of the main output. This happens at

the first voice "hit" of the DJ or speaker on the microphone (or line) plugged to channel. When

the DJ stops talking, the music level comes up to the initial level. This function is enabled

through the TALKOVER (8) switch, and has efficiency, EFF (19), i.e. main signal level

attenuation (between 0 and 30dB) and recovery time, TIME (9), the time necessary for a

progressive come back to the original level (between 0,1 and 3 sec).

The Talkover can be activated by channel 4 if certain internal jumpers for the bus-

assignment are re-soldered. See configuration diagram.

This modification must be performed by an Authorized Technical Service.

4.6. Outputs

The COMPACT5 mixer has two independent outputs, OUTPUT 1 (30-31) and

OUTPUT 2 (29). Each one has its own volume control.

You must be careful when setting up the general output level of the mixer. The "clip"

display of the connected power amplifiers must never remain permanently lit, but do it only

occasionally by following the rhythm of the bass signals that are being played.

The OUT1 output (30-31) is balanced or symmetrical, and the pin-out of the

connector is as follows:

Hot or direct signal > Pin 2

Cold or inverted signal > Pin 3

Ground > Pin 1

The balanced circuit simulates an output transformer, so if you wish to use OUT1 in

non-balanced mode, you should short circuit the unused pin to ground. Otherwise, the signal

will not have an appropriate level and quality.

The OUT2 output (29) is non-balanced or asymmetrical.

The COMPACT 5 has one recording output REC (32), which is pre-talkover, i.e. no

signals which activate the talkover are passed to this output, so no attenuation occurs).

5. CONSIDERATIONS

5.1. Ground loops, background noise

You should always make sure that the signal sources coming to the unit, as well as all

devices connected to its outputs, do not have their grounds interconnected, that is; ground must

never come from two different devices. Should this ever happen, noises could occur and seriously

interfere the sound quality.

Cable shielding, when connected to the chassis, must never be interconnected, so as to

avoid ground loops.

The COMPACT 5 mixer has been designed for the lowest possible background noise.

Independently from the electronic design itself, background noise level will directly depend on the

right installation and use of the mixing unit.

I. e.: setting a channel VOL to "2" and the output to "10" is not the same as the other

way round. In the first case, the signal coming to the mixing amplifier - which has got its own

noise - is low, and so is the signal-to-noise ratio (low signal). When the output amplifier boosts the

whole signal we will get a very high background noise. In the second case - with the channel

fader at maximum - the mixing level is high, and so is the signal-to-noise ratio. When the signal

reaches the VOL OUTPUT and is boosted, it will keep a much better signal-to-noise ratio than in

the preceding case.

5.2. Cleaning

The front panel should not be cleaned with dissolvent or abrasive substances because

silk-printing could be damaged. To clean it, use a soft cloth slightly wet with water and neutral

liquid soap; dry it with a clean cloth. Be careful that water never gets into the amplifier through

the holes of the front panel.
